Abstract
A communications system has a plurality of remote stations linked to a master station via three channels, two of which are data channels, and one of which is a signal channel. The two data channels carry time multiplexed digital signals to and from the master station respectively. The signal channel is used by all the remote stations for initiating communication with the master station, which in response to a remote stations signal allocates to that remote station a particular time slot. The system may be part of a satellite communications system, or it may be combined with a cable television distribution network.
